Miami Open: Defending champion Hubert Hurkacz advances, Daniil Medvedev stops Andy Murray, Naomi Osaka gets walkover
Hubert Hurkacz unleashed 17 aces to topple France's Arthur Rinderknech 7-6(5) 6-2 and keep his title defence going at the Miami Open on Saturday as world number two Daniil Medvedev sent twice winner Andy Murray packing and Naomi Osaka advanced on a walkover. Rinderknech was unable to convert his sole break point in the first set and lost the momentum altogether after the tiebreak, as the 10th-ranked Pole won the first four games of the second set of their second-round clash. Reigning U.S. Open champion Medvedev never faced a break and proved too nimble for three-times Grand Slam winner Murray, dropping just two of his first-serve points in the second set as he won 6-4, 6-2.
